  • Patent number: 9745624
    Abstract: Homogenous detection during or following PCR amplification, preferably LATE-PCR, utilizing fluorescent DNA dye and indirectly excitable labeled primers and probes, improves reproducibility and quantification. Low-temperature homogeneous detection during or following non-symmetric PCR amplification, preferably LATE-PCR, utilizing fluorescent DNA dye and indirectly excitable labeled mismatch-tolerant probes permits analysis of complex targets. Sequencing sample preparation methods following LATE-PCR amplifications reduce complexity and permit “single-tube” processing.

  • Patent number: 9476092
    Abstract: A non-symmetric polymerize chain reaction (PCR) amplification method employing a limiting primer in low concentration whose concentration-adjusted melting point at least equals, and preferably exceeds, that of the excess primer, the latter in turn not being more than 25° C. below the melting temperature of the amplicon. Assays employing such amplification and labeled hybridization probes, including assays that include a detection step following primer extension or a low-temperature probe, or both. Kits for performing such assays and primer or primer-and-probe sets for performing the foregoing amplifications and assays.

  • Patent number: 9279121
    Abstract: Biological samples containing nucleic acids, RNA and DNA, are freed from bound proteins by incubation with a chaotropic agent such as a guanidium salt, and the mixture is readied for further processing by dilution of such agent to a concentration below 0.05 M without physical isolation of RNA and DNA from one another or from other components of the reaction mixture. Methods include such preparation and further processing, such as amplification and detection, which may be performed in a single container. Chaotropic agent may be supplied as a dried reagent adhered to a container. Kits may include such reagents, alone or with amplification reagents.

  • Publication number: 20120198576
    Abstract: Embodiments of the invention are based upon the discovery that exposure of cleavage-stage embryos to a stress inducer, e.g. heat shock or chemical, renders the exposed embryos more sensitive to a secondary treatment with a stress inducer, e.g. heat shock or chemical inducer. Accordingly, the present invention is directed to methods for making embryos, embryonic cells arising from them, and animals and plants that are sensitized to stress, e.g. physiologic or chemical stressors. Methods of screening for inducers and inhibitors of stress using, as test model systems, embryonic cells, embryos, animals, and plants that are sensitized to stress are also disclosed.
